Arguments concerning Twitter’s growth are more common than ever, but Twitter hasn’t topped out yet, at least.  A new report from comScore indicates that the site managed to attract about 19 percent more unique visitors in June than in May. 

Here’s some additional good news for fans of Twitter: if you look back to June of 2008, the site’s growth rate is an astounding 1,460 percent.  Also, Erick Schonfeld writes, "ComScore now counts it as the No. 52 largest site in the world (bigger than ESPN, just shy of the BBC and Craigslist)."

That’s a noteworthy stack of statistics.

Unfortunately for Twitter, there are a few other things to take into consideration.  For example: the deaths of Farrah Fawcett, Michael Jackson, Billy Mays, and Ed McMahon all occurred in June, and generated tons of chatter.  A month-over-month bump of 19 percent seems a little small considering the circumstances.

Then there’s the report indicating that Twitter received $48 million in free media coverage during late May and most of June to take into account.  And really, a 19 percent month-over-month bump isn’t especially huge, regardless.

Let the arguments over Twitter’s popularity continue, then.
